Abstract (en)
[origin: WO2009043352A2] The invention relates to a method for de-icing a blade (5) of a wind turbine (1), after the wind turbine (1) has been idle for a period of time. The method comprises the steps of creating a controlled acceleration condition of the blade (5), and subsequently creating a controlled deceleration condition of the blade (5), whereby ice is shaken of the blade (5). The invention further relates to a wind turbine (1) comprising a rotor including at least one blade (5), and de-icing means for de-icing the blade (5) wherein the de- icing means comprises actuating means (19) of the wind turbine (1) and wherein the de-icing means further includes control means for performing a method according to any of claims 1 to 11. Furthermore, the invention relates to use of a wind turbine.
